I'm designing a table saw extension for my DeWalt DW745. I've searched for plans and most of them add an out-feed extension to the table saw.
I'd like to cut some dadoes and rabbets in wide boards (>40cm), but set at 2cm high (just a random small height), my table saw only has about 17cm of clearance between the blade and the beginning of the table, so it gets kind of clumsy.
Also, I'd like to use a crosscut sled with said wide boards, but I'm not sure something so big would work without an in-feed extension.
I'm aware that adding in-feed extension would make it difficult for me to access the controls of the machine.
So, would just adding a side extension help me with these problems? Why is it so uncommon to have in-feed extension, at least I haven't seen a single plan which uses it.
